IMPROVED BOOT-HEEL POLISHER.

Specification forming part .of Letters Patent No. 72,105, dated December 10, 1867. i

by declare that the following is afull, clear,

and exact description thereof, reference being had to the accompanying drawings,rin which- 'F1gure l is a perspective view of my ina- `chine, and Fig. 2 is a detached view ofthe clutch which holds the boot-heel.

Ais the frame which supports the operative machinery. B is a pulley-whcel,to which the power is applied to give rotary motion to its shaft b. On the opposite end. of this shaft is rigidly fixed an eccentric wheel, c, which revolves within a metal hoop or band, c', to which is attached a pitman, p, which is piv oted at its opposite end to an oscillating crank, D, which carries the polisher D'. Rotary motion being given to the shaft b, an oscillating motion is given to the crank D by means of the eccentric wheel c and thev pitlnan p, and this oscillating motion of the crank gives the polisher a reciprocating motion in the line of an arc of a circle. The stem d, to which the polisher is attached, slides in a sleeve, s, and is pressed down by a spiral spring, s', which gives the polisher an elastic bearing on the boot-heel, and allows it to yield to the irregularities thereof` F is the frame or rest in which the boot or shoe is suspended. This frame is mounted on a sliding base-piece, H, which allows the boot or shoe to be moved to or from the polisher, and it turns horizontally on a pivot, j'. This pivot ts into a vertical sleeve or socket, c, which extends down into a slot in the basepiece of the frame A. Said pivot f is movable vertically in said sleeve or socket, and is held in any desired position by a set-screw, the sleeve turning with the pivot f. By this means the frame F is adjustable vertically, to suit varying sizes of the boot or shoe to be operated u on.

'pThe boot or shoe is held in the upper part of the frame F by means of a toothed plate or clutch, g, (shown in a separate figure, 2,) again st which the bottom of the heel is pressed, and a screw-shaft, h, which enters a sockethole in the top of the last, opposite the heel. Said clutch g revolves on the end of the shaft to which it is attached, and the end ofthe screw-shaft h enters the holein the last loosely enough to allow the last to turn freely thereon, so that by turning the boot vertically and the frame F horizontally, all parts of the heel to be polished may be brought in contact with the polisher.

Having thus fully described my invention and its inode of operation, what I claim as new,

'viviAN K. sPEAa.
